Big Jack - seed from contest Ganja Farmer

Hello mates, third week of vegetation for Big jack. She had a gorgeus growth a week after the topping of the past week(10/10), the rigth equilibrium between internodal distance and new sprouts growth, big and healty leaves with an intense green. Badly in the 11/10 i noticed the tipical sings of Ca defiency on the lower fan leaves of Big Jack in a light form and on the other plants in the tent so this meant i did something wrong with my Ca/Mg rate in the base water. I checked again how much grams of Epsom salts i must put in the base water and there finally i found my fucking mistake, i was 10x wrong about the unit of measurement. I always put 0.2 g/L of tap water and this was the mistake because i should have put 0.02 g/L, I completely reversed the problem of the tap watear that normally have more Ca than Mg. She finished this week in a optimal condition despite that inconvenient in fact i did a defoliation and a pruning in the lower part of the plant, more or less under the 50% of the hight.
